Lauren Spierer's parents, Robert and Charlene and sister Rebecca Spierer, listen as Lt. Bill Parker (not shown) updates media representatives last June on the search for their daughter, Lauren Spierer. in Bloomington, Ind.

The parents of a Westchester college student who went missing while at school in Indiana last June said for the first time this week they no longer believe their daughter is alive.

Charlene and Robert Spierer told The Journal News in their first interview in months they're now "trying to be realistic" about their daughter Lauren's whereabouts.

"We know that if she had the chance to reach out to us, she would have done it," said Robert Spierer.

Lauren Spierer's parents have maintained a low profile in recent months, but they told the paper they have not given up on their efforts to find their daughter.

Massive Search for Missing NY Student

"I feel if she never met Corey Rossman, she'd be alive today," said Robert Spierer, referring to one of the students she went out with that night. "His claim of memory loss is laughable."

Rossman returned to Spierer's building after they'd gone to a bar, and he told police he left after he was confronted by several people in the hallway, according to The Journal News. He said he was punched so hard he lost memory of the night.

Video surveillance shows Rossman helped Lauren Spierer out of her building after she came stumbling out of her elevator, according to the newspaper.
